Method and apparatus for treatment of respiratory disorders

A method of treating a respiratory disorder, the method comprising:

• supplying, upon initiation of treatment, a flow of pressurised air from a pressure device to the airway of a patient at a treatment pressure one or more positive pressures according to a pre-sleep profile of pressure versus time,
• increasing, upon detection of sleep onset of the patient by a controller of the pressure device, the treatment pressure one or more positive pressures to a predetermined therapeutic pressure according to a bridging profile of pressure versus time, and
• supplying the flow of pressurised air to the airway of the patient at a therapeutic pressure,
• wherein the controller of the pressure device is configured to detect the sleep onset by detecting:
• few or no respiratory disturbances occurring within a predetermined interval, the predetermined interval being a predetermined time or predetermined breath count, wherein, by monitoring respiratory flow derived from a flow transducer, the controller detects few or no respiratory disturbances to detect the sleep onset by testing lack of variation during the predetermined interval of expiratory peak flow location.

Apparatus for treating a respiratory disorder comprising:

• a pressure device, and
• a controller, including at least one processor, configured to control the pressure device to:
• supply, upon initiation of treatment a use by a patient of the apparatus, a flow of pressurised air to the airway of a the patient at a treatment pressure one or more positive pressures that commences commence at a pre-sleep pressure and varies vary according to occurrences of sleep disordered breathing events,
• increase, upon detection of sleep onset of the patient, the treatment pressure one or more positive pressures to a predetermined therapeutic pressure according to a bridging profile of pressure versus time, and
• supply the flow of pressurised air to the airway of the patient at a therapeutic pressure,
• wherein the controller is configured to detect the sleep onset by detecting:
• few or no respiratory disturbances occurring within a predetermined interval, the predetermined interval being a predetermined time or predetermined breath count, wherein, by monitoring respiratory flow derived from a flow transducer, the controller detects few or no respiratory disturbances to detect the sleep onset by testing lack of variation during the predetermined interval of expiratory peak flow location.

• adjust, upon detection of sleep onset of the patient, the treatment pressure one or more positive pressures according to occurrences of sleep disordered breathing events, and
• supply, upon the treatment pressure one or more positive pressures reaching a predetermined therapeutic pressure, the flow of pressurised air to the airway of the patient at a therapeutic pressure,
• wherein the processor is configured to detect the sleep onset by detecting:
• few or no respiratory disturbances enduring for a predetermined interval, the predetermined interval being a predetermined time or predetermined breath count, wherein, by monitoring respiratory flow derived from a flow transducer, the processor detects few or no respiratory disturbances to detect the sleep onset by testing lack of variation during the predetermined interval of expiratory peak flow location.
